In addition to this, non-competative online games generally are safer. Look into the individual games you're interested in, but something like WoW or FFXIV should still work fine, Last Epoch or PoE2 work.
Stuff like Lethal Company (Platinum) or Rust (Bronze) are more case by case, depending on the anticheat they use, and even then it's often a matter of whether the developers include support or not.
Space Marine 2 uses an anticheat, but they have support enabled for Linux (though they removed it in one of the patches, before reimplementing it).
(Also a slight pet peeve to OP, it's "right off the bat")
